A clustered Virtual Machine may end up on the wrong switch after move

When you have a VM clustered on multiple Hyper-V Hosts it is necessary that the machine configuration (XML) is modified to reflect the correct Switch Name on the new host during move. The Configuration file for the VM holds GUID values for "SwitchName" and "PortName". As the VM is configured with a readable Switch Name like "External" it is essential that this Switch Name exists on all participating Hyper-V hosts, and even with the same case. So upper and lower case letters need to be identical!
